Honest, Hard Working

Bellomy Heating and Air services our commercial office buildings. They are always honest, hard-working and informative. They do our regularly scheduled maintenance as well as help us update and replace ac units and systems that are old. They always give us a rate quote with several options. Grant or Randy alre always willing to explain everything. They are also very responsive in situations where we have needed something done right away. Ten years ago, this company also put in a unit in my personal home. This is a great family-owned business. Very trustworthy and knowledgeable. I highly recommend it.

Integrity and Professionalism

I am not someone who usually post reviews. But I can't say enough about Grant Bellamy. He arrived on time, he was courteous, and professional. He made sure that he explained the issues so that a layman like myself could understand. Mr. Grant runs his business with integrity and professionalism you don't see any more. I will be using his services in the future and I would recommend him and BIMS to anyone.
